Assembly The assembly couldn’t be easier. Only a screwdriver is needed to tighten up the four screws that fix the Voyager to the base of the HDD. Then, just put HDD inside the case as usual and connect the cables. Testing It’s time to focus exclusively on its performance. We began by using a HDD which temperature was already stabilized. As it is well known, the most effective way to dissipate heat from a HDD is by cooling its aluminum sides. In spite of that, it’s easy to appreciate that the hottest spots, at least among the external spots of the HDD, are located in the HDD logic board. To get a clearer idea of what was really happening to it, two thermal probes were put in those places that were previously detected as the hottest in the logic board, and a third one was put on the side of the HDD. This layout was enough to find out that the report delivered by the HDD through S.M.A.R.T (Self Monitoring Analysis and Reporting Technology) was the same as the hottest spot in the logic board. Knowing that the internal report of the HDD matched up with the worst condition that was manually taken with external sensors, we continued with the test, taking this fact as reference and basing our work on it. The probe installation would not be complete if the external side wasn’t insulated. In this way, it can be guaranteed that the temperature taken is that of the HDD and not a combination of both HDD and air. To carry out the test, the IDLE condition of the HDD –although it wasn’t in absolute IDLE mode- was achieved by working on a HDD without operating system, programs, nor anything that required an access to it. By simply letting the PC ‘rest’, we would make the HDD remain in a state of relative inactivity. However, to work in FULL condition, we didn’t let it rest: a 37 Gb folder was copied from the primary HDD (which takes approximately 13 minutes), and also several specific programs for HDD testing were executed.
The behavior was completely satisfactory, as it achieved a decrease in temperature of 8°C in both working conditions. In each of the four tests, not less than six runs were carried out to be sure that the results were the correct ones. It is important to mention that we looked for the highest values in FULL and the lowest in IDLE, and that in every conducted test the room temperature was 24°C.
